Engineered for non-contact, high-reflectivity precious metal joining. Explore catalog items below with immediate factory quotes available for overseas procurement.
From micro-electronics wire bonding to luxury horology restoration, precious metal joining has evolved from oxy-propane flame micro-torches to wavelength-tuned solid-state and quasi-continuous wave (QCW) lasers.
Gold has an extraordinary thermal conductivity (approx. 318 W/m·K) combined with extremely low optical absorption (<5% at room temperature for 1064nm infrared). Traditional micro-torches cause structural collapse and overheat adjacent gemstones like emeralds and pearls.
Modern gold welding systems utilize millisecond pulse profiling, achieving localized melt pools that freeze instantaneously without annealing neighboring structural alloys.
In conventional jewelcraft, lower-karat soldering pastes adulterate purity, trigger hallmarking downgrades, and cause seam tarnishing over time. Micro-laser fusion achieves autogenous autogenous butt and seam welds.
By utilizing parent-metal wire feeding or micro-spot fusion, luxury manufacturers prevent loss of precious material and guarantee karat authenticity without chemical flux pickling.
Driven by rising labor costs in Europe and the Americas, large-scale jewelry and medical component factories are shifting away from purely manual benchtop microscopes to galvanometer scanning and 3-axis CNC stages.
Automated batch spot-welding of gold chain links, medical implants, and sensor pins achieves repeatable micron precision at speeds exceeding 50 spots per second.
When specifying capital machinery for precious metal manufacturing, understanding the physics behind photon generation and laser beam modulation is critical for selecting the proper architecture.

Gold laser welder pricing is dictated by four major technical variables: Laser Source Type (Nd:YAG flashlamp pumped vs. QCW solid-state fiber), Peak Energy Capacity (Joules per pulse, typically ranging from 40J for fine jewelry to 120J+ for dental and heavy casting repair), Optical System Quality (German Leica or Japanese Olympus stereo microscope integration, motorized beam expanders, high-definition CCD crosshair monitoring), and Level of Automation (manual joystick benchtop vs. multi-axis CNC / galvanometer tracking systems).
Gold possesses extreme optical reflectivity (over 95% at standard 1064nm wavelengths in its solid room-temperature state) and extraordinary thermal conductivity. To successfully create a melt pool without burning out alloys, the laser machine must deliver high initial peak power (pulse spiking) to overcome reflectivity, followed by a modulated cooling pulse profile to prevent hot cracking and shrinkage voids.
Yes. Because laser welding delivers energy in sub-millisecond bursts (typically 0.5ms to 20ms) focused down to a 0.2mm diameter, the heat-affected zone (HAZ) is microscopic. Master jewellers routinely weld prongs within 0.2mm of diamonds, sapphires, rubies, and cubic zirconia without inducing thermal shock or clouding, saving hours of tedious stone unset-and-reset bench time.
High-purity Argon gas (99.999% industrial purity) is universally recommended. Argon prevents atmospheric oxidation of copper or silver alloys present in 9K, 14K, and 18K gold compositions, eliminating dark soot stains and producing bright, mirror-finished weld beads directly out of the chamber with minimal finishing required.
